'IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent N0. 171,751, dated January4, '1876; application filed November 15, 1875.

To all whom it may concern Beit known that I, ANDREW WIGGIN, of

vthe city of Boston, in the State of Massachusetts, have inventedcertain Improvements in Oarbureters 5 and I do hereby declare that thefollowing, taken in connection with the drawings which accompany andform part of this specification, is a description of my inventionsufticient to enable those skilled in the art to practice it.

The object of my invention is to accelerate and increase thevaporization of the fluid during the passage of the gas through thecarbureter; and it consists in the method and means hereinafterdescribed for eecting this end.

A is an ordinary Vessel for" containing the gasoline or otherhydrocarbon or equivalent material, and it may be provided, ascustomary, with an appropriate inlet-tube, B, andwith a flexible orjointed tube, C, for the admission of street or other gas or air, and anoutlet-tube, D, for the exit of the carbureted gas or air, these tubeshaving appropriate cocks. It has also acock or inlet, E, through which aliquid 'may be supplied, and which may also serve as a vent. It mayalso, it desired, have an indicator to signalize when the vessel issufliciently iilled.

The parts thus far named, not being my invention, need not be furtherdescribed, and I will now proceed to describe my novel devices and theiroperation, and which appertain' mainly to the floating gas-chamber F,with which the lower end of the flexible or jointed tube C connects.

This gas-chamber I construct in a peculiar manner, with especialreference to insuring the exposure to the gas of a larger surface thanheretofore of the saturated absorbent, and to the insuring of a long andwinding passage to the gas, during all of which passage it is beingbrought into contact with the liquid and with this increased surface ofthe absorbent.

Figure 1 is a vertical y section of a carbureter illustrating myinvention 5. Fig. 2, a plan of the floating chamber or conveyer.

The flexible tube C connects directly to a short vertical metallic tube,G, 4which forms the central or starting point for the horizontalcircuitous course or route of the incoming gas in its distribution. Thistube G, which rises higher than the absorbent material hereinafternamed, communicates by an opening at its vertical side with a winding orspiral gas or air conveyer' or distributer, H, having perforations inits vertical sides for the proper exit ofthe gas throughout its wholelength, the conveyer H being narrow in its horizontal cross-section, andrelatively much `'broader' in its vertical section, such constructionpermitting it to be of great length, and consequently to present acorrespondingly largesurt'ace in proportion to the diameter ordimensionsof the vessel A. The conveyer, at its outer wind or coil, terminates ina large circle; of a size somewhat less than the diameter of thevesvwhich should be partially immersed in the liquid, an annularair-containing float, I, is connected, as shown,'to the windingdistributer, the latter preferably passing directly through it, in orderto permit the outer ring of the distributer to be outermost. Thebuoyancy should besuch as to permit the distributer to be only partlyimmersed in the liquid. It is evident that the tloat or buoy maybe ofany desired form, and connected with the distributer in any suitablemanner. Between the winds or coils of the distributer H are spaces J forthe reception of sawdust, sponge, or any appropriate absorbent, and suchabsorblent should also be placed above the distributer to any suitableheight., The top or cover may have a glass-covered opening provided, bymeans of which the quantity of liquid introduced may be ascertained byinspection. This glass should be inserted in a .removable cap, which maybe screwed on and of. (See sectional Fig. 4.) It will, of course,- beunderstood that the floating distributer will rise and fall with theliquid as .it may be supplied or consumed, the flexible tube permittingsuch movement, and its outer ring or coil need not be perforated, asthere will not be any absorbent on its exterior face-z'. c., between itand the wall oi' the vessel. A cylindrical reticulated or perforatedrim, K, extends upwardfroln the outer ring to hold any desired quantityof absorbent upon and above the distributer. I prefer that theperforations in the sides of the distributer should gradually increasein size or in number, (orin both, ifdesired,) in proportion to theirdistance from the center,

' so that those which are nearest the center of y the coil shall permitbut a small proportionate quantity of the gas to be ejected throughthem, and so that it shall continue `to be ejected and distributedthroughout its-whole length with approximate uniformity proportionate tothe increasing surface circumscribed by the successive coils of thedistributer. Fig. 3 shows projected upon a plane one of the sides of adistributer thus perforated.

It will now be seen that as the gas makes `its lateral exit through theperforations it passes directly into the thin body of saturatedabsorbent lying between two adjacent coils or windings of the.distributer, and

also saturated with the liquid, serves through out its Whole mass stillfurtherto charge with vapor the ascending gasor air. `The coilmay reston cross-strips or onaperforated bottom.

It' desired, the vessel A may have an inner perforated lining, and thespace between them may be filled with 1an absorbent, and I provide itwith a tube or passage, l, open at its bottom, and designed forconnection at its top with the filling cock or inlet F. f
